Where to find 5/8 bolt on sprocket and hub?

[Doodle Bug Jr.]

Does anyone know where they sell these types of 4 bolt hub and sprockets in 5/8 for a jackshaft? The only ones I could find were 1 inch for go karts. Thanks in advance.

There are some NOS Bonanza sprockets on ebay. Not sure about the hubs though.

I was looking for the same thing a couple years ago...

I wanted a jackshaft sprocket with a lot more teeth than normal to drop the top speed on my bike and increase the take-off.

I tried Grainger...they have a decent assortment of industrial sprockets...but they only sell to registered businesses, so they won't help retail consumers.

I ended up welding a 40t sprocket to a smaller 5/8" jackshaft sprocket with the teeth turned off in a lathe...worked fine in the end.

there's a Grainger store just up the street from my house and they'll sell to you if you just go in there.

Thanks, Im gonna look into that. The ones on ebay are perfect if I can find a hub or make one. I wonder if aluminum would be strong enough?

surpluscenter.com has sprockets up to 50+ tooth for a 5/8" shaft...
the 60+ have 3/4" bore and up..
Just a heads up if you need J/S sprockets in odd sizes, they have 'em.:wink:
